Had another look at this over the weekend started from cold ok and drove with a hesitation when put under load but as it got warm it was idling rough and when i opened the throttle it would not rev and was misfiring and popping back in to the air filter. have checked live data and the oxy sensor seems to switch for a few mins then goes dead have replaced and checked wiring to oxy sensor 1 have tryed disconnecting the afs and tried removing the oxy sensor from the exhaust just incase the exhaust is blocked but still the same can anyone help thanks ALAN
